地球物理方法的研究是一门不断发展的科学，可以解决各种各样的目标 在地下水调查中。然而，由于地球物理方法的成功应用 根据调查人员可用的技术、后勤和专业知识，不可能 针对所有病例规定的一套现场程序或方法。BS PD ISO/TR 21414:2016提供 有助于为各种目标（包括 在现代仪器和解释技术的限制下， 都提供了。本文重点介绍了更常用的现场技术和实践 关于电阻率、电磁和地震折射技术，因为这些技术在地震中被广泛使用 地下水勘探。文中提到了解释程序的理论方面和细节 仅以一般方式。有关详细信息，请参考中列出的专门文本 参考书目。购买本文件时可获得的所有当前修订均包含在购买本文件中。

The of geophysical methods is an evolving science that can address a variety of objectives in groundwater investigations. However, because the successful application of geophysical methods depends on the available technology, logistics, and expertise of the investigator, there can be no single set of field procedures or approaches prescribed for all cases. BS PD ISO/TR 21414:2016 provides guidelines that are useful for conducting geophysical surveys for a variety of objectives (including environmental aspects), within the limits of modern-day instrumentation and interpretive techniques, are provided. The more commonly used field techniques and practices are described, with an emphasis on electrical resistivity, electromagnetic, and seismic refraction techniques as these are widely used in groundwater exploration. Theoretical aspects and details of interpretational procedures are referred to only in a general way. For full details, reference is intended to be made to specialized texts listed in the Bibliography.All current amendments available at time of purchase are included with the purchase of this document.
